One used M/A-COM MACOM H360 Circulator Isolator in UHF Band tuned to 440-450MHz, But Tuneable over the range of 406 to 512 Mhz. Includes one Celwave 30Watt Load. Every unit tested to meet factory specs. Insertion loss of 0.4 dB typical. All units have N-Type connectors.
Actual photos show some blemishes, but are fully functional. See my listing in other frequency ranges or with other loads. We also have 3 db Hybrid couplers to build transmitter combiners.The vast majority of users are fine with the 30 watt load on a 100 watt repeater. One possible exception, should the coax cable short near the transmitter while operating at a high duty-cycle such as paging, you would need a 100 watt load. But most repeaters operate intermittent and most failures occur at or near the antenna. For example, if your feedline loss is 1.5 dB to the antenna and your antenna failed, with an VSWR of 10:1 with 66% of the power reflected. Then you are losing 29% [1.5dB] of your power reaching the antenna and the bad antenna is reflecting 66% back down the feedline for another 25% feedline loss for a total of 33 intermittent watts into the 30 watt load. With that bad of antenna, few users would be using the repeater.
